Energy Saving

So, in my Japanese class, prompted by the text we'd just read or grammar point we just learned or whatever, the teacher asked us to describe things we can do to save energy.

- One could use the low-consumption light bulbs.

- We can turn off computers when we don't use them.

- Turn off the lights while taking a shower.

- We can... wait, what?

Apparently, in Argentina (and also Australia, according to our Argentine source), they turn off the lights while they're taking a shower.

- You mean, all the lights outside the bathroom?

- Yes, and also in the bathroom too.

A collective "Huh?!?".

- At night too?!?

- Yes, of course, at night too. We often sing in the shower, so the government made a campaign to switch off the lights during the shower to save energy.
